The new Festool ks-glide with quick-fix motor change capability. Never wait for customer service to replace your burnt motor again. Limited time promo version comes with 2 spare motors in a green systainer (nevermind they sold out while you read this ad).

So he figured out to copy Bosch's design, the Chinese do that every day, turn around, and sell the copy for huge profits with near zero R&D costs.Nothing to be proud of there as far as I am concerned.

So, if you built, for example, a Roubo workbench you can't be proud if it because its a copy? Bosch copied that design too. That double articulated arm style is at least 100 years old. BTW pendulum mortiser, aka Domino, is also a century old. It's not as if he's trying to patent or sell it. Just a fun DIY project.
